Thank you Hans... but it doesn't fully work. Now I only enter the input
once (that's ok) but on the second run, the variable is not defined
anymore. How can I keep it in the conTeXt memory?
-- Minimum still not working example
local name
if environment.arguments.currentrun == "1" then io.read() end
context.startdocument()
context("Hello " .. name)
context.stopdocument()
All the best
